Installation on Ubuntu 20.04

@SPlatten Not really Qt related. You should ask this on the forum related to the broken Debian you use.

My guess would be that downloaded file doesn't have exec permission. Righ-click on the file, [Properties], "Allow file execution" or similar.
Alternatively from the console: "chmod +x qt-unified-linux-x64-4.0.1-1-online.run"

That should fix your issue but I would also allow for the risk that this system is more broken than usual.

This is unrelated to the distribution used, the file just has no execution permission which is fine in itself.

Hi
Its default on ubuntu.
https://help.ubuntu.com/community/InstallingRunPackage

As else it would be very Windows alike to allow to run anything pr default:)

[SPlatten]

@artwaw , @SGaist , @KroMignon , @mrjj , thank you all, sorted now...

[artwaw]

@SGaist In theory, yes. Downloaded files should always have execution bit missing. But this is ubuntu, you never know if it will behave like a proper Linux should.

Not sure what you mean: it behaves exactly like it should, executable bit is not set for downloaded files.

[artwaw]

@jsulm I am not questioning that. In this particular case.

Why do you say this? It sounds like Ubuntu bashing?!?

I use Ubuntu and/or Debian since many years, it works as it should.
Most of the time system error occurred when I force something what the system did not allow ;)

So now having installed Qt from that link, Qt Creator itself will not launch. Any suggestions on how to fault find?

[artwaw]

@KroMignon Bashing might be a bit of a strong word but I detest *buntu deeply. Having to work with those over the years I become very cautious as it tends to break in the least suitable moments. Maybe for purely desktop use it is ok, I admit to lack of experience in that regard. In every other aspect it is... Full of surprises, let's say. Of course, still better than most other distros.

@SPlatten what exactly happens? Have you tried to run it from the icon, menu, console? Any messages?

[jsulm]

@SPlatten Try to start it from the terminal and see whether there are any errors.
Also try to start it with "-noload all" parameter to see whether it makes a difference.

@artwaw , @jsulm , dam it, Virtualbox isn't new and still seems buggy as hell, Shared Clipboard & Drag'n'Drop both set to Bidirectional, neither work.

I've opened a terminal and typed in:

sy@sy-VirtualBox:~/.local/share/applications$ ./org.qt-project.qtcreator.desktop: line 1: [Desktop: command not found
./org.qt-project.qtcreator.desktop: line 3: fg: no job control

Obviously from the list above there are prerequisites required that are not present. Is there a guide on how to get up and running? I was following an online guide by Qt, but I didn't think I had to manually go through the huge list of downloads?

Did you install VirtualBox extensions?
I use Ubuntu 20.04 in a VirtualBox VM on Windows7 and Windows10 host and copy/past or shared clipboard just work.

I hope you did not install Qt as administrator on your Ubuntu VM?

@KroMignon said in Installation on Ubuntu 20.04:

t as administrat

It could be the macOS variant of Oracle VirtualBox. The user I'm using on Ubuntu is a standard user not super user.

Sorry, I never used macOS, can not really help you :(

[SPlatten]

@KroMignon, apart from the GUI, its Linux.

I have done nothing special:

• download the installer from Qt (was an older one 3.1.1)
• set execution bit: chmod a+x qt-unified-linux-x64-3.1.1-online.run
• launch installer: ./qt-unified-linux-x64-3.1.1-online.run
• install required packages: sudo apt-get install build-essential libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386

that's it

[SPlatten]

@KroMignon , perhaps its an issue with the version of Qt I'm trying to use?

Maybe, I don't know, you could try to download an older one here => https://download.qt.io/archive/online_installers/3.2/

I haven't done any of this download stuff, just looking at your output.

I don't know why you think this is to do with missing prerequisites. It looks like that is being executed as a shell script file where something is wrong? Is it really supposed to be executable??
